Michael,
I wonder if you might have a bit of RF floating around that is
confusing the issue and perhaps giving you false meter readings?
Since it is band specific it might be the case.
Maybe a slightly different length of coax between the rig and linear
would change things; perhaps a little different grounding. It's all
a big experiment!!
